It has a cross-sectional structure.

の問題が生じていた。 However, in the case of such conventional skis, those with a sole structure of FRP have a low response, and those with a laminated structure of a combination of FRP and thin sheet metal, or those with a single structure of thin sheet metal,
Good response, but elastic limit (maximum strain) is 0.7~
Because it is as low as 0.8%, various problems have occurred when used under harsh gliding conditions, such as sagging, insufficient arch bend recovery, and a decline in gliding performance.

合せ積層されている。 As shown in FIG. 1, numeral 1 in the figure is a ski according to the present invention. The ski 1 includes a core body 2 made of foamed synthetic resin, FRP layers 3, 3 laminated on both upper and lower surfaces of the core body 2, and both upper and lower FRP layers 3, 3,
The main body of the sanderch structure is composed of two amorphous metal sheets 4, 4, which are interposed and laminated symmetrically in the ski width direction in the ski width direction. A ski upper surface component consisting of a surface decorative sheet 6 made of ABS resin and a ski lower surface component consisting of a sole edge 7 and a running surface plate 8 are integrally combined and laminated.

る。 By the way, the amorphous amorphous metal sheet interposed and laminated in the above-mentioned FRP is, for example, Fe32−Ni35−, which was announced by Allied Chemical Company (USA) under the trade name "Metglas".
Consists of a multi-element alloy composition such as Cr15−P12−B6,
Thickness is narrower than the ski width, for example, from a minimum of 10mm to a maximum of 50mm, and a board width is from a minimum of 10mm to a maximum of 50mm.
mm, using a plate with an elastic modulus of 10.5×10 3 Kg/mm 2 ,
To embed and laminate in FRP, green material for FRP molding with glass cloth reinforcing fibers on the bottom side (reinforcing fibers impregnated with matrix uncured synthetic resin and semi-cured as necessary) A raw material for FRP molding with glass roving reinforcing fibers is placed on the upper side, sand-chilled, and cured to form an amorphous metal sheet embedded in the FRP layer. It is formed by laminating and molding a metal sheet with an FRP plate interposed between the metal sheet and the core, and as a result, the strength member according to this invention can increase the elastic limit (maximum strain) to 1.8%. It became. In addition, although the above example shows the case where a foamed synthetic resin is used as the type of core material, the present invention is not necessarily limited to this, and even if other types of materials such as wood are used, the effects of the present invention can still be obtained. can be obtained.

ものである。 As explained above, according to the present invention, since an amorphous amorphous metal sheet is interposed in FRP, which serves as a strength member, energy loss is smaller compared to FRP alone, and ski repulsion characteristics can be improved. In addition, it is possible to prevent the arch bend from becoming bent due to harsh skiing conditions as in the past, and to improve skiing performance, which has excellent practical effects.
